Combining creativity with

a hallmark of duke dot edu.

The Duke Blue Devils are you, students learning and
creating. As we approach Blue Devil Days, we hope that
each of you will be an ambassador to those students who have been
admitted to Duke, and are deciding if this is the right place for them.

Duke is a great place, where great things can happen. You can
do research, you can play a sport, you can engage society. Or you can do
all of that! Becoming an effective cyber citizen is something
you can each do! That's part of the outcome in this course.

Logging your visit here can benefit students in both sections
of Compsci 342s, in Compsci 92, and in Compsci 201 --- in these
courses professors have pledged to add points to the final exam
for every different IP address that's logged when you authenticate
your visit. For every 20 unique IP addresses, one point will be
added to a final exam. If your course doesn't have a final? You
can help others!

Is this ethical? Is this just a phishing expediation to see who
clicks on the link here? Points-per-click seem reasonable.
